BELT-BUCKLE.

Specication of Letters Patent.

Patented May 18, 1920.

Application led May 8, 1919. Serial No. 295,595.

To all lzii/tom it may concern Be it known that I. SAMUEL BUCHSBAUM, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented a certain new and usefulImprovement in Belt-Buckles, of which the following is a full, clear,concise, and exact description, reference being had to the accompanyingdrawings, forming a part of this specification.

My invention relates to belt buckles and has for its object theprovision of a new and improved clasp or holding means for retaining thefree tongue of the belt in any desired position. My invention has forits prime object the construction of a clasp of this nature, which inits simplest form consistsV of a single piece of metal punched andformed into shape to fulfil all of the requirements of a device of thischaracter.

The clasp structure in its simplest form consists of a movable claspelement coperating with the buckle base plate. The movable vclaspelement is movably carried by the base plate and has means forpreventing its dislodgment from its permanent location.

I will describe one form which my invention will take, more in detail,by referring to the accompanying drawing, in which-- Figure 1 is aperspective View of a belt buckle constructed in accordance with myinvention;

Fig. 2 is a side view thereof;

Fig. 3 is a bottom view thereof ;V

Fig. 4 is a sectional view online 4-4 of Fig. 1; and Y 5 is aperspective view of the adjustable clasp element.

Fig. 6 is a fragmentary sectional view illustrating a modified form ofmy invention, and

Fig. 7 isa perspective view of the modified form of adjustable claspelement shown in Fig. 6. Y

By referring more particularly to the figures, I show a buckle baseplate 10 having thefront wall 11 and two rearwardlyex tending flanges orside walls 12. At the left hand extremity of the base plate 10 there isa pivotally carried clamping structure 14 which is designed permanentlyto clamp in lposition the extremity 15 of the belt. The

free belt tongue 16 is then held in position in any desired portion ofits length through the agency of my improved structure as will presentlyappear. The clamping structure 14 includes a pivotally mounted element17 having the pins 18 by virtue of which it is pivotally carried in theside walls 12 of the base plate 10. This element 14 carries the clampingcam 19 for permanently locking the belt extremity 15 to the element 14.The

belt extremity 15 is thus pivotally supported in the buckle base plate10. I

My improved clasp structure for holding the belt tongue 16 consists ofthe movable clasp element 20 which cooperates for clasping purposes withthe base plate 10. The movable clasp element includes a bridge structure21 having at its extremities proeetions 22 by virtue of which the claspelement is slidable in slots 23 formed in the side walls 12 of the baseplate. The side walls 12 are bent into their present position after thebridge structure 21 with its projections 22 has been placed in itsallotted position. My improvedV clasp element has backwardly extendingshoes or guides 24, 24, at the top and bottom thereof7 which prevent aswinging movement of the said clasp element in the plane of the slot 23.These shoes or guides 24 thus prevent dislocation of this movable claspelement relative to the belt base plate 10. The structure, however, issuch that the movable clasp element may slide longitudinally of theslots 23. It will be noted that the slots 23 slope forwardly toward thefront wall 11 of the base plate 10 so that a movement of the movableclasp element from left to right will bring the inner edge of the bridgestructure 21 closer to the wall 11. In this manner the belt tongue 16 islocked in position between the front edge 13 of the movable claspelement 20 and the front wall 11 of the base plate 10. When it isdesired to withdraw the tongue 16 it is pushed to the left and theprojections 22 held by the fingers, whereupon the belt tongue can bewithdrawn. It will be also noted that the backwardly eX- tending shoesform effective means to hold the front edge 13 of the movable claspelement 2O in its locking position to prevent any large amount ofrotation of said movable clasp element about the axis of the projections22. movable clasp element 20 can be formed from a single blank of metal,the parts being bent into their appropriate positions, thus providing avery simple device of this nature.

Referring to Figs. 6 and 7, I show a modi- It will also be seen that thelied structure 20 of my improved clasp elenient provided with a bric gestructure 21a having sidevvardlvextending shoes 0r guides 246% Theseshoes 24E? serve to prevent dislocation of the clasp element relative tothe' base plate. Y

While l have herein shown and particularly described several forms whichmy invention may take, what I claim as new and Walh said flattenedprojections and slots per- Y mitting only a limitedsivinging movementolf said clasp relatively to the plate.

2. A device of the character described comprising a Vbaseplate havingiront and Vside Walls7 said side Walls having inclined guidesand amovable clasp element pivotally and slidably mounted in said guides;v

and having a limited sivinging movement relatively to the plate andadapted to clamp the free extremity of a belt tongue against said frontWall, said clasp element engaging the belt at opposite sides of itspivot.

3. A device of the character described comprising a' base plate havingfront and side Walls,V said side Walls having guides, and a movableV-shaped clasp element slid- `ably mounted in ysaid guides, and adaptedto engage the belt at a plurality of points to clamp the free extremityof the belt tongue against said iront Wall. d. A device of the characterdescribed comprising a base plate having front and side V7walls,V saidside Walls having inclined slots, and a movable Vclasp element slidablymounted in said slots and having a limited pivotal movement therein, andadapted to clamp the free extreinityioi: Ya belt tongue against saidfront Wall, said movable clasp element having auxiliary guide-meanscoperating vvith said base plate for maintainin said clasp element inproper relationship to its slots. Y

5. A device of the character described Acomprising a baseV plate havingfront and sidewalls, said sidewalls having inclined guides, and amovable clasp element slidably mounted in said guides, and having alimited pivotal movement therein, and adapted v to clamp the freeextremity of a belt tongue against said front Wall, saidmovable claspelement having auxiliary guide means coperating with said base plate formaintaining said clasp velement in proper relationshipto its guides.`

6. A device of the character described comprising a base plate havingi'ontand side Walls, said side Walls having guides, and a movable claspelement slidably mounted in said guides, and adapted to clamp the freeextremity of a belt tongue against said wall, said movable clasp elementhaving auxiliary guide means cooperating With said base plate formaintaining said clasp element in proper relationship to its guides,

`and a second clamp element pivoted on said plate and adapted to havethe otler end of the belt secured thereto.
